“Look, Gov. Romney’s going to be the nominee, and he’s going to have enough votes,” said Bennett, who is publicly neutral but said he supported Romney four years ago.

Romney’s chief rival, former Pennsylvania Sen. Rick Santorum, is vowing to stay in the race, hoping a win in his home state’s primary on April 24 will give new life to his campaign. But Santorum has fallen far behind Romney in the race for convention delegates, and RNC members are taking notice, even though most are publicly staying neutral, preferring to let primary voters decide the nominee.

The Associated Press has polled 114 of the 120 RNC superdelegates, party members who can support any candidate for president they choose at the national convention in August, regardless of what happens in primaries or caucuses.

Results from the latest survey conducted Tuesday to Friday: Romney has 35 endorsements, far more than anyone else but a modest figure for the apparent nominee. Gingrich has four endorsements, Santorum has two and Texas Rep. Ron Paul got one.

RNC members have been slowly embracing Romney — he picked up 11 new endorsements since the last AP survey a month ago, after the Super Tuesday contests. Over the course of the campaign, however, Romney has methodically added endorsements from every region of the country. And in the U.S. territories, where voters help decide the nominee but can’t vote in the general election, Romney has dominated.

Romney has endorsements from all three RNC members in Guam, American Samoa, the Virgin Islands and the Northern Mariana Islands. He was endorsed by two of the three RNC members in Puerto Rico.

Romney may be struggling among voters in the South, but he was endorsed by two of the three RNC members in Mississippi, Henry Barbour and Jeanne Luckey. Romney even has support from RNC member Robert Asher of Pennsylvania, the state Santorum represented in the Senate.

Santorum’s only endorsements are from RNC members in Iowa and Alabama. In Pennsylvania, state GOP chairman Robert Gleason is publicly neutral.

“I talked to Rick the other day,” Gleason said. “He didn’t even ask me to support him.”

Texas GOP chairman Steve Munisteri said he talked to Santorum for about 20 minutes on Tuesday, when Santorum was in Texas for a fundraising event.
